Add "compatibility" property for zpool feature sets Property to allow sets of features to be specified; for compatibility with specific versions / releases / external systems. Influences the behavior of 'zpool upgrade' and 'zpool create'. Initial man page changes and test cases included. Brief synopsis: zpool create -o compatibility=off|legacy|file[,file...] pool vdev... compatibility = off : disable compatibility mode (enable all features) compatibility = legacy : request that no features be enabled compatibility = file[,file...] : read features from specified files. Only features present in *all* files will be enabled on the resulting pool. Filenames may be absolute, or relative to /etc/zfs/compatibility.d or /usr/share/zfs/compatibility.d (/etc checked first). Only affects zpool create, zpool upgrade and zpool status. ABI changes in libzfs: * New function "zpool_load_compat" to load and parse compat sets. * Add "zpool_compat_status_t" typedef for compatibility parse status. * Add ZPOOL_PROP_COMPATIBILITY to the pool properties enum * Add ZPOOL_STATUS_COMPATIBILITY_ERR to the pool status enum An initial set of base compatibility sets are included in cmd/zpool/compatibility.d, and the Makefile for cmd/zpool is modified to install these in $pkgdatadir/compatibility.d and to create symbolic links to a reasonable set of aliases.

Adding new read-only compatible zpool features to compatibility.d/grub2 GRUB2 is compatible with all "read-only compatible" features, so it is safe to add new features of this type to the grub2 compatibility list. We generally want to include all compatible features, to minimize the differences between grub2-compatible pools and no-compatibility pools. Adding new properties `livelist` and `zpool_checkpoint` accordingly. Also adding them to the man page which references this file as an example, for consistency.
